Continually assess the wind effect and new snow amounts as you move through terrain. Wind and storm slabs will likely remain reactive to rider traffic.

Wind and storm slab reactivity could increase if the sun comes out.

Summary

Confidence

Moderate

Avalanche Summary

Ski cutting continues to produce small wind slabs and dry loose avalanches.

No other significant avalanches reported in the past few days.

Snowpack Summary

Up to 20 cm of new snow has fallen past 24 hours. At higher elevations this sits over extremely wind affected surfaces including large sastrugi. Many west facing alpine areas may not hold new snow and instead be stripped back to hard surfaces.

A melt-freeze crust with facets above, sits 50 to 120 cm deep. It has not produced any avalanches.

The mid to lower snowpack is considered well bonded at this point. Currently we are not seeing the same basal weak layers and reactivity that many of the neighboring regions are experiencing this season.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be alert to conditions that change with elevation and sun exposure.
